I just want to throw it out there that when people say "I don't want to lose muscle" or "I want to "preserve my precious muscle", they are talking about muscle size. Not muscle power or strength. Hobby cycling does not need 'Stronglifts', 'Starting Strength', or 'Crossfit' as adjunct programs. What I suspect the o.p. wants to begin is a more or less standard bodybuilding routine. A Bench Press performed 3 sets x 10 to 12 reps is a very different beast than a Bench performed 5 sets x 5 reps in its effects on a persons appearance over time. The cycling won't care either way, but for me anyway, the bodybuilding approach fits better with what I want to see in the mirror.
